A woman carries a a baby past a 340-ton megalith rock, which is to be part of artist Michael Heizer's artwork "Levitated Mass", as it is seen on a transport vehicle in the middle of the road, about 5 miles from downtown Los Angeles on Friday. The massive granite boulder is on the last leg of an 11-night, 106-mile journey to the Los Angeles County Museum of Art where it will become the centerpiece of artist Heizer's 'Levitated Mass.' It is expected to arrive in the early morning hours on Saturday and will take weeks to put in place before the installation opens to the public in late spring or early summer. The $10 million cost to move the boulder was paid for by the museum through private donors.

The museum finally worked out a route that went around freeway overpasses, stayed away from bridges and avoided narrow streets to enough of a degree that everybody was satisfied. The total project is costing $5 million to $10 million.

"It's funny, the Egyptians didn't have rubber wheels and diesel trucks to move things. But they also didn't have 22 cities through which they had to move their stones," museum director Michael Govan noted recently.
